Embodiment

[0022] Such as figure 1 and image 3 ,or figure 2 and Figure 4 As shown, the multi-chamber prefabricated pipe jacking manufacturing method includes a concrete pipe jacking joint 1, a reserved steel bar connector 2 and a post-cast concrete wall 3 arranged in the concrete pipe jacking joint 1, and the specific steps are as follows:

[0023] Step 1: Use a general mold to make the concrete pipe jacking joint 1, and set a reserved steel bar connector 2 in the concrete pipe jacking joint 1 during pouring;

[0024] Step 2: After the concrete pipe jacking joint 1 is demoulded, lie down the pipe joint, and pour the post-cast concrete wall 3 in the concrete pipe jacking joint 1; the steel bars of the post-cast concrete wall 3 are connected with the reserved steel bars Connector 2.

[0025] The principle of the present invention is that the concrete pipe jacking joint 1 and the post-cast concrete wall 3 are successively produced in the factory, no custom-made molds are required dur...

Abstract

The invention discloses a multi-cabin prefabricated jacking pipe manufacturing method. The multi-cabin prefabricated jacking pipe comprises a concrete jacking pipe joint, reserved steel bar connectorsand a post-cast concrete wall, wherein the reserved steel bar connectors and the post-cast concrete wall are arranged in the concrete jacking pipe joint; the manufacturing method comprises the following steps that S1, the concrete jacking pipe joint is manufactured through a universal mold, and the reserved steel bar connectors are arranged in the concrete jacking pipe joint when the concrete jacking pipe joint is poured; S2, after the concrete jacking pipe joint is demolded, the pipe joint is laid down, the post-cast concrete wall is formed in the concrete jacking pipe joint, and the steel bar of the post-cast concrete wall are connected with the reserved steel bar connectors. According to the method, the pipe joint is made of the universal mold, a mold is not required to be customized,the partition wall is laid and poured in a factory after the pipe joint is demolded, and the jacking pipe has the characteristics of being convenient to manufacture and flexible in separation.

Description

technical field [0001] The invention relates to the technical field of pipe jacking, in particular to a method for manufacturing multi-chamber prefabricated pipe jacking. Background technique [0002] With the development of society and economy, there are more and more underground projects such as underground vehicle tunnels, underground pedestrian passages, and underground comprehensive pipe corridors. In the above projects, pipe jacking is a common construction method. When pipe jacking is used for this type of work, it may be necessary to divide the internal space. [0003] There are usually two methods to solve such problems in engineering: [0004] 1) Customized pipe jacking molds with partition walls, prefabricated in the factory; [0005] 2) After the on-site pipe jacking is completed, the partition wall shall be constructed on site by means of brick masonry, cast-in-place concrete or prefabricated wall panels. [0006] Although the quality and progress of the pip...
